Bitcoin is the first cryptocurrency that was introduced in 2008 by the pseudonymous Satoshi Nakamoto. Bitcoin isn’t just digital money, but a combination of technologies that enables peer-to-peer value transfers without the need for intermediaries.

The Bitcoin blockchain is a chain of blocks operating on a distributed network of computers that interact and share data with each other. The participants of the network are called nodes. Each blockchain node holds a copy of the Bitcoin database, and they communicate whenever new data is recorded. Bitcoin nodes participate in the process of verifying transactions, ensuring that the network data is secure and immutable.
